Java 初始化及种的加载

Java 初始化及类的加载
下面是Think in Java中的一段代码，自己加了几行

package reusing;import static net.mindview.util.Print.*;class Insect {private int i = 9;protected int j;private int x2 = printInit("Insect.x1 initialized");Insect() {print("i = " + i + ", j = " + j);j = 39;}static {System.out.println("Init Static block");}{System.out.println("Init block");}private static int x1 = printInit("static Insect.x1 initialized");static int printInit(String s) {print(s);return 47;}}public class Beetle extends Insect {private int k = printInit("Beetle.k initialized");static {System.out.println("Beetle static block");}public Beetle() {print("k = " + k);print("j = " + j);}private static int x2 = printInit("static Beetle.x2 initialized");private int x1 = printInit("Beetle.x2 initialized");public static void main(String[] args) {print("Beetle constructor");Beetle b = new Beetle();}}

分析其类加载的过程：
         （1）首先加载当前类，再加载当前类的父类，直到加载到基类，然后执行基类的static代码块，再执给基类里面的static成员变量赋值，赋值完成之后再执行子类里面的static代码块和给static成员变量赋值，以此类推。
（2）static块和成员赋值为完成之后回到基类中，给其余的非static的成员变量赋值，再执行非静态块，然后是构造方法，完成之后回到子类中继续按（2）处执行

上面的代码执行结果是：
Init Static block
static Insect.x1 initialized
Beetle static block
static Beetle.x2 initialized
Beetle constructor
Insect.x1 initialized
Init block
i = 9, j = 0
Beetle.k initialized
Beetle.x2 initialized
k = 47
j = 39
